+# 实验六
+
+## 1.实验目标
+1. 掌握Android网络访问方法；
+2. 理解XML和JSON表示数据的方法。
+
+## 2.实验内容
+1.在个人目录中创建一个表示数据的XML或JSON文件；
+2.数据文件代码提交之后从GitHub获取文件URL；
+3.在应用中通过网络编程访问GitHub的数据文件；
+4.在应用中解析并显示文件所包含的数据；
+5.将应用运行结果截图。
+
+## 3.实验步骤
+由于实验目的用不上原本实验六的网络编程功能，所以实验六在原来的基础上做修改。把原Information页的“读取资料卡”的显示功能由悬浮的显示改为固定的Textview。
+
+1.在info的xml里面新增三个Textview

+
+## 5.实验心得
+设置Textview的方法和editText的方法大同小异，就是要在activity显示的时候，要用textview.setText来实现。
